In penal institutions and the like it is very desirable to have the glazing seated in channels on all sides, so that the inmate cannot very well without discovery peel away the putty'and re-. move the glass.

Furthermore, it is desirable to mount the .detention bars in spaced relation from the masonry along the bottom of the window to prevent corrosion. Use has demonstrated, particularly in packing houses and wherever subjected to steam and to chemical fumes, the life quality of the bottom horizontal portion of a steel window is shorter than the life quality of other portions of the window. The reason for this is that. such portions are partially embedded or inaccessible for repainting and therefore retain moisture and dampness. Detention windows are also liable to have a similar weakness due to the type of steel used in detention bars. Erosion of the detention bars, resulting in failure, may be disastrous, creating public danger.

This has been overcome in the present embodiment by arranging a frame structure that terminates in spaced relation from the masonry extending along the bottom of the window. By so doing, no metal comes in contact with the masonry. The space between the masonry along the bottom of the window and the lowest portion of the metallic frame structure is closed by glaze ing, having the upper edge seated against the lowest portion of the metallic frame and the lower edge secured directly to the masonryextending across the bottom of the window by putty or other suitable plastic material. 7

In the present invention an arrangement 0f channels has been made wherein it is possible to seat the glazing in channels on all sides without having a side of the ohannelremovable. This has been accomplished by providing oppositely disposed end channels, at least one ,of which is sufliciently deep to pass-the window pane into the channel and slip the opposite edge of the window pane into the other end channel. In order to do this it has been found necessary to make the channel along one side of the window pane sufliciently wide so as to provide clearance beyond the face of the muntin bar for the window pane. In other words, the channel in the wall has been made sufiiciently wide so as to extend beyond the inner face of the muntin bar a distance sufliciently great to accommodate the thickness of the glazing.

Referring to the drawings, the reference character 20 indicates a plurality'of vertically dis- 20 posed detention bars having the upper ends seated in the masonry 22 bounding the ventilating area.

zontal portion 28, a shoulder and a sloping portion 32. It has been found that the detention bars that are embedded in the masonry extendlng across the bottom of the window rust and deteriorate very rapidly. In order to eliminate this rusting and deteriorating of the detention bars, the lower ends of the detention bars have been arranged in spaced relation from the masonry extending across the bottom of the window.

In order to provide a satisfactory support for the lower portion of the detention bars, the lower duo-functional rail and muntin bar designated by the reference numeral 34 has been spaced only a short distance from the masonry extending across the bottom of the window. It maybe only an inch, two inches, or possibly four or five inches from the bottom: The duo-functional rail and muntin bar 34 may be of heavier material than the other rail bars, so as to prevent the inmates from bending or distorting this duo-functional rail and muntin bar. In some respects, the duoiunctio'nal rail and muntin bar may be referred I to as a sill supporting the lower end of the detention bar 20.

The duo-functional rail and muntin bars 24 and 34, respectively, are preferably provided with a horizontal portion 36 terminating in a downwardly projecting flange 36 extending along the outside of the detention bars 20. The opposite end of the downwardly sloping portion 36 supports and is integral with an H-shaped portion 40.

The upper channel 42 being smaller or shallower than the lower channel 44, these channels receive the glazing as will appear more fully later.

As the duo-functional muntin and rail bars 24 and 34 respectively, have their outer ends seated in the masonry bounding the window, the outside frameof the conventional windows has been eliminated. In this respect, this is similar to my Patent No. 2,020,046.

The channels along the sides of the window may be formed by attaching a suitable formmember 54 to the rail bars and-muntin bars 24 and 34. In the modification disclosed in Fig. 7 a vertical spacer bar 56 has been fixedly and permanently attached to the duo-functional rail and I 5 the insertion of the window pane without pro-' viding a removable side for the channel. The channel to the left of Fig. 2 may be formed by a rigid form member shown in Fig. 11. Member 55 and its resulting channel 52 need not be wider than the channels 42 and 44 found in members 24 and 34.

The glazing 10, as may best be seen by refer-- ring to the dot and dash position shown in Fig. 3, is positioned in offset relation, extending into the channel 50 so as to clear the wall contining channel 52. The glazing when in this position is in readiness for rotation in the bottom channel in the direction of the arrow I2 into the full line position. After it has been rotated so as to have the lower edge of the window pane seated in the channel 42, the window pane is moved from the dot and dash position shown in Fig. 2 to the full line position, was to have the edge shown to the right of Fig. 2 seated in the channel 52 which is narrower than the channel 50 shown to the left of Fig. 2. It is necessary to have only one of the channels sufliciently wide to extend beyond the fact of the duo-functional muntin and rail bars 24 and 34 respectively.

In the modificationfdisclosed in Fig. 8, members 54 and 56 have been omitted; but instead of these a form member 14 has been used, which is considerably wider than the depth of the channel 50. This permits the use of a wire 16 passed through the opening 18 in the horizontal portion 36 of members 24 or 34, as the case may be. The

form member 14 is provided with suitable holes for the passage of the wire 16. In order to properly straddle the H-shaped portions of the muntin bars 24 and 34, member 14 has been provided with suitable notches. Members I18 have been placed in the channels'42 and 44 to prevent concrete from filling the ends of the channels. After the and member 14 removed fromthe face of the wall bounding the window opening, so as to vacate the channel 50. v

For some'types of structures it is desirable to face the channels 50 and 52 with a suitable metallic member. Then removably mounted form concrete has been poured the wires 16 are cut" members such as 54 or 14 may be omitted, the

metallic channel members performing the same function. In Fig. 5 a U-shaped member 60 has been used. It passes through suitable apertures provided thereforiin the muntin and rail bars 24 and 34. This member is provided with a pair of reentrant flanges 82 seated in the edge of the concrete.- Tongues 84 may be struck out from the U-shaped member 80 to further support it in the masonry. I

In the modification disclosed in Figs. ,6 and 13, tongues 66 have been struck out from-the legs of the U-shapedmember 86 at spaced intervals and embedded in the concrete; By referring to Fig. 13 it may be seen that the tongues 86 are also used to hold member 66 in fixed spaced relation with respect to the bars 24. The tongues quately hold member 88in position without ex may be arranged .in'staggered relation to adecessively weakening the same.

Referring to the modification disclosed in Fig. 14, a pair of metallic members 90 and 92 cooperate to form the channel 50 without either member being passed through the muntin and rail bar. Instead, the L-shaped member 90 has-one flange 94 welded to the faces of the rail and muntin bars 24 and 34. Member 90 is preferably made from comparatively heavy material, thereby giving rigidity to the window assembly to facilitate handling at the factory, in shipment and during erection of the structure. Furthermore, no filler members are needed while pouring the concrete. Member 98 preferably extends continuously throughout the entire height of the window opening. Member 92, on the other hand, is preferably of a suitable length to fit between adjacent muntin bars, so as to span the approximate width of each window pane.

Whenever the windows are comparatively wide, it may be desirable to reenforce or support the sill muntin and rail bar at spaced intervals. In the modification shown in Figs. 10 to 12 this has been accomplished by a cast iron pipe I00 having its lower end embedded in the masonry 26 and the upper end encircling the lower end of a detention bar 20. The pipe I00 fits snugly into the space between the downwardly projecting flange 38 and the end of the detention bar 20 and into the space between the H-shaped portion 40 and the bar 20. The flange 3B and sill of each window. Although cast iron is far ift more rust resistant than the material used in the muntin bars 34 and the detention bars 20, other more non-corrosive material may be used in these pipes, such as brass, copper, Duralumin, tile, or other metallic or vitreous material.

The pipe I00 preferably has a web I02 welded or otherwise attached thereto, adapted to project between adjacent window panes. In addition to forming seats for the glazing, the web I02 reenforces the pipe so as to give the assembly more rigidity.

Instead of a round or tubular member I00 having the web I02 and the shoulders I04, any other suitable reenforcing member may be used. This member may be provided with anchoring means in the masonry. For other types of structures the reenforcement may be accomplished by an upwardly extending concrete projection, or the like, to provide a rail support.

Although the preferred modification of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts which generally stated consist in a device capable of carrying out the objects set forth, in the novel parts,
